AutoCAD Civil 3D :: Drawing In Coordinate Systems

Nov 6, 2012

If I set up my Civil 3D drawing in some known coordinate system, e.g. State Plane, in the "drawing settings", can I then toggle my drawing into other known systems, e.g. UTM, by changing the coordinate system under "drawing settings"?

If not, how are the coordinate settings used?

AutoCAD Civil 3D :: Using Multiple Coordinate Systems At Once

Jul 14, 2012

I'm finding myself on more and more sites that use multiple coordinate systems and height datums.

We have 3 on this job. One is the MGA zone 50 GDA94, another is just an offset of this and the third is a strange local grid with offsets and rotations.

We have Excel spreadsheets that can convert between the systems, but that requires several extra steps per point.

Is it possible to define each coordinate system in one drawing so that I could select which system I wanted to use, input the points and then select the main coordinate system so it converts the coordinates directly? It would mean less steps and I would have greater confidence in this system. 

We have the parameters for all systems.

AutoCAD Civil 3D :: Data And Different Coordinate Systems

Aug 1, 2012

I have a problem with different coordinate systems. I have a drawing in old Finnish coordinate system (KKJ, kaista 4) and I have a point file, which is made in ETRS-GK29 coordinate system. When I try to transfer the points to the drawing, the points will land way off from the drawing or I get this error message "Coordinate transformation from ETRF89.FinlandGK-29 to FINL-KKJ4 failed for point located at {29511662.554000,6948599.365000}. This usually indicates the point falls outside the boundaries of the destination coordinate system". I have checked and the point {29511662.554000,6948599.365000} should be over the drawing.

AutoCAD Civil 3D :: Disappearing Coordinate Systems

Jul 9, 2012

My Civil 3D 2012 coordinate systems normally displayed on the units and zone tab of the drawing settings have disappeared.  On existing drawings the coordinate system code is still displayed.  On new drawings the code appears as a symbol - a period or a comma or something.  I can enter the coordinate system code and the program recognizes it.

My Civil 3D 2011 coordinate systems display as expected.

AutoCAD Civil 3D :: Unable To Change Coordinate Systems While Importing Points

Nov 3, 2012

I want to know why I can't change coordinate of points while importing points from Points menu?

I created new file, assigned any coordinate system to the model. Opened Import points windows there, created new file format which there I assigned Coordinate zone transform to the coordinate system of the text file and imported my text file. But the coordinates of points didn't changed or transformed. When I do it by Survey in Toolspace its works good. I want to know whether I did any wrong or it is problem of software.

I use AutoCADCivil 2013 64 bit in Windows 7 64 bit!

AutoCAD Map 3D :: Multiple Coordinate Systems / Units?

Jul 17, 2012

I'm enlisted in the United States Air Force and am working with the Navy for topo surveys.  I'm bringing my information into AutoCAD Map 3D 2010 and using the coordinate system UTM84-4N.  I can't figure out why when I bring in my survey .dwg, all of the points are in the middle of the ocean. 

I've tried to manually project the coordinate systems onto each file and reference them.  I've changed units to meters.  I've copied with base point 0,0 and pasted as the same.  I've even opened a fresh file, gave that a projection, imported the drawing from "Map Explorer" and queried "ALL" and redrew the file and still nothing.  I've checked the Geo-Markers and they're obviously off.  Is there a way to match them and have it scaled properly?

AutoCAD Inventor :: Default Sketch Coordinate Systems?

Jan 30, 2012

Is there a way to set Inventor so that the sketch origin defaults to the part origin?  I find it very frustrating that it always defaults to some random corner of the part's body.  It can screw up a part if you decide later on to modify the part such that you eliminate the point to which a coordinate system was defined.  Also, when copying and pasting a sketch to new work planes it can be a pain to figure out which point is the origin of the orignal sketch if the pasted sketch is misaligned. 

I know you can edit the coordinate system after a sketch is created, but I'd prefer not to have to rememember to do that with every sketch.

This was brought up about 6 years ago and there was no formal resolution


In the second-to-last post John-IV8SP1mentions an option under 'Application Options' for an older version of AI, but I cannot find it in the 2012 applicaton options.

AutoCAD Map 3D :: Image Coordinate Systems Transformation And Rotation?

Apr 1, 2010

I have some UTM images that I need to convert to State Plane. If I import them into map with raster design and export them to the state plane coordinate system, they work just fine, but I can't figure out a way to get rid of the black wedge that it makes along the edges of images.

If I query them in using map I can transform the coordinate system, but then every time I open the drawing it takes like 5 minutes just to open.

What has everyone else done to use multiple images in a drawing and transform or convert the coordinate system of the images?

AutoCAD Map 3D :: How To Create Multiple Unique Coordinate Systems

May 17, 2011

A - Autodesk will fix them in a timely fashion during this release - Not holding my breath here

B - Others won't spend hours trying to figure it out.

In my case, I need to create multiple unique coordinate systems called Low Distortion Projections (Google it for explanation.)

Here are the problems identified so far with the 2012 version of the Coordinate Library

Coordinate System Categories

1 - The regional 'containers' that hold coordinate systems definitions. You cannot create an empty container. It requires at least 1 coordinate system definition to be created. When creating a container put an arbitrary coordinate system definition in. This assists with item 2b.

Coordinate System Definitions

2a - Getting started - There is no provision to just select an existing datum or ellipsoid. One must 'create' a new definition that may vary in name only. The vast majority of us using their products will not actually create new ellipsoids or datums just utilizing them as the basis for other projections.

2b - Creating definition - Continuing the definition process the definition needs to be placed in a coordinate system category. Due to the problems identified in item 1 this creates a circular error. The workaround being item 1 rather than creating multiple definitions in the wrong container then going back to fix them.

2c - Scale Reduction - This should be renamed to Scale Factor to fit with the rest of the known world as the value can be greater or less than unity (1.000000) In my case the values all happen to be something greater than 1. While on this subject, the autodesk programmers set this to do something totally unexpected. No matter what you set the value to, if you save and reedit the projection value will be displayed as '1'

2d - Missing Projection definition form data - I went through the projection definitions and found the following projection types were missing their fields in the form:

AutoCAD Civil 3D :: Translating Drawing Including All Design Work To New Coordinate

Jul 23, 2013

I am 90% into the design of a subdivision and the survey was just updated.  The original design was in an arbitrary coordinate system, and the new boundary is in state plane coordinates.  I would like to move all of the design information to the new boundary.  This would include all of the surfaces (approximately 6).

When I move the surface (any surface), I end up with errors.  If I move the surface alone, I cannot move the defining feature lines.  If I move the feature lines, I loose all of the edits I have made to the surface.

Is there any clean way to translate a drawing, including all design work, to a new coordinate?

AutoCAD 2010 :: Drawing From Surveyor In Rotated Coordinate System

May 17, 2013

I received the attached drawing file "A" from a surveyor that was created in an earlier version of AutoCAD (approx 2000).  The attached drawing is rotated so that the view in Model Space shows the cross-hairs with north pointing northwest.  There are points included within the drawing that do not match the coordinates of the surveyed points within the attached ascii text file.   I would like to rotate the drawing so that the points match the coordinates in the ascii file and North follows the y-axis.  

I have imported the points from the ascii text file into a new drawing file "B".   I external referenced (overlay) the new drawing file B into drawing A.  I tried moving all of the objects in the drawing file A (with MOVE) to a known point coordinate and then rotating (ROTATE) the objects to two known points. I don't know how to select all of the objects in drawing A and not the external reference in drawing B so that I may Rotate only drawing A objects.

How to move and rotate the surveyors drawing A so that I may match the coordinates in the ascii text file.

AutoCAD Civil 3D :: DWG Coordinate System Transformation?

Nov 20, 2012

My group is trying to convert a dwg from one coordinate system to another. The original drawing contains points, blocks, etc. in 1 system and we need it in a different one. We tried attaching the dwg to a new map with the new system using a layer query, but this did not appear to bring in the objects into the new system.

"Structures" is in the original system (OR83-NF), "StructuresHarn" is in the desired system (ORHP-NIF)

AutoCAD Civil 3D :: Coordinate Transformation Results

Feb 21, 2012

I am using Civil 3D and Map 3D 2010.

I have some points in a drawing set up in a coordinate system and using a specified point file format, I successfully exported them to another coordinate system for use by our surveyors. I also wanted the pipe route in my destination drawing so I created a shp file from a polyline representing the pipe route in the original drawing using Map 3D Export. When I imported the shp file into my destination drawing there appears to be a slight horizontal difference from the point locations. The shp file doesn't land directly on the points.

To try another comparison, I ran a query on the pipe route to perform a manual coordinate system transformation. The result of this is the exact same as the shp file.

My questions are, which method (exporting points vs. shp files) results in the correct coordinate transformation and why are they different? When exporting points I am not using any specific transformation settings, I am simply selecting the destination coordinate system. When exporting a shp file, Map 3D creates a prj file from the specified coordinate system in the drawing. Are there any other settings I need to adjust to get the same result with both processes? The only thing I can think of is I only have the coordinates out to 4 decimal places in my point file format, do I need to go out farther?
